Dispensing container for acetylene



Patented Nov. 7, 1950 DISPENSING CONTAINER FOR ACETYLENE Martin H.Heeren, Chicago, Ill., assignor to National Cylinder Gas Company,Chicago, 111., a

corporation of Delaware No Drawing. Application March 22, 1945,

Serial No. 584,262

1 Claim. 1

This invention relates to the storing of acetylene under pressure incylinders or receptacles filled with a solid absorbent materialimpregnated with an acetylene solvent. Hitherto the solvent used forthis purpose has been acetone, but the use of this substance isassociated with certain disadvantages arising from its ready volatility.For instance, on rapid discharge of acetylene from a filled cylinder asmuch as 3% or 4% of the acetone is lost. Further, chilling of thecylinder due to evaporation of acetone on discharge of acetylene coolsthe cylinder to the point where the solubility of the acetylene in theacetone is appreciably increased. As a consequence, relatively largeamounts of acetylene gas are retained in the cylinder instead of beingdis-' charged.

It is therefore an important object of the presis stored under pressurein cylinders or receptacles containing a suitable porous absorbent suchas the filler disclosed in the patent to Smith No. 1,332,525 comprisingPortland cement, diatomaceous earth, asbestos fiber, charcoal and water.This or some other equivalent absorbent filler is impregnated with 2,4pentanedione (acetyl acetone).

As is usual in acetylene storage technique, the

gas should be dried before contact with a solvent; preferably it shouldbe passed over calcium chloride before and after compression. The usualpressures may be employed, namely from 10 to 30 atmospheres. The amountof acetylene dissolved is the same as that usually taken up byconventional volatile solvents such as acetone.

The loss of 2,4 pentanedione on rapid discharge of acetylene fromstorage cylinders is but a fraction of the loss noted when acetone isemployed as the solvent.

Many details of composition and procedure may be varied within a widerange without departing from the principles of this invention, and it istherefore not my intention to limit the patent granted on this inventionotherwise than necessitated by the scope of the appended claim.

I claim as my invention:

Dispensingv container for acetylene gas under pressure comprising acylinder or receptacle ca.- pable of being closed and of withstandinginternal pressure, a porous, absorbent mass filling said cylinder orreceptacle, a substantial quantity of 2,4 pentanedione absorbed in saidporous mass, and acetylene gas dissolved in said 2,4 pentanedione to bereleased therefrom for delivery from said cylinder or receptacle whenthe latter is opened.
